Introduction

Managed switching of up to eight Gigabit Ethernet ports is performed by the Marvell® Prestera® 98DX4122 Gigabit Ethernet Switch Controller and Marvell's Routing OS. An embedded web server provides a convenient and intuitive graphical switch management interface via a web browser. Command line switch management is also supported over network and RS-232 connections.

PCIe switching of up to 20 ports / 24 lanes is performed by the IDT 89H32NT24AG2 Gen2 PCIe switch, which provides powerful switching capabilities and integrated DMA engines for fast data transfers between VPX cards. Flexible configuration options allow setting of different port/lane combinations and allocations for Transparent and Non-Transparent ports.
